摘要:
以聚丙烯/热塑性聚氨酯(PP/TPU)80/20共混切片为原料,采用相应的工艺进行熔喷,从而制备出以TPU为“岛”PP为“海”的海岛型复合纤维结构的熔喷非织造布。并对纤维的横截面形态和纵向形态,非织造布的厚度、透气量、拉伸强度及弹性回复性能进行了表征。试验表明,高黏度的TPU与低黏度的PP混纺仍有一定的熔喷可纺性。试验发现:当其条件保持不变,只改变热风温度时,随着热风温度的升高,纤维的平均直径及熔喷非织造布的厚度呈逐渐减小的趋势;而熔喷非织造布的透气量及拉伸强度呈逐渐增加的趋势。同时发现,PP/TPU熔喷非织造布手感柔软,具有一定的拉伸强度和弹性回复性。
Abstract:
The melt-blown nonwoven fabric with “Sea-Island” composite fiber structure (TPU as “island component” and PP as “sea component”) was prepared with melt-blow technology by PP/TPU (80/20) blended slices. cross section form and longitudinal form of fibers as well as thickness, air permeability, tensile strength and elastic recovery of the nonwoven fabric were characterized. The test result shows certain melt-blown spinnability in the blends of high viscosity TPU and low viscosity PP. When other conditions kept unchanged and only hot air temperature was changed, the average fiber diameter and the nonwoven’s thickness decreased with the rise of hot air temperature. The air permeability and tensile strength of nonwovens increased. The hand feel of this PP/TPU melt-blown nonwoven fabric is soft and the fabric has certain tensile strength and elastic resilience.
